THE EFFECTS OF FIELD EMITTED ELECTRONS ON RF SURFACE
| Description | Accelerator cavities with a thin film of Niobium are known to perform reliably from experience gained at previous particle accelerators. New coating techniques like High Power Impulse Magnetron Sputtering (HiPIMS) has shown very promising results at coating cavities with niobium. Current materials used in accelerator Superconducting Radio Frequency (SRF) technologies operate at temperatures below 4 K, which require complex cryogenic systems. Researchers have previously investigated the use of High TemperatureSuperconductors (HTS) to form RF cavities, with limited success. The research group investigated a new approach to achieving a high-temperature superconducting cavity based on the superconducting 'proximity effect'. The superconducting proximity effect is the effect through which a superconducting materialin close proximity to a non-superconducting material induces a superconducting condensate in the latter. Using this effect may allow the research community to overcome the problems that have prevented the use of HTS for accelerating structures so far. Initial results are interesting but no definitive conclusions could be drawn. |
| Exploitation Route | The development of thin films for superconducing rf cavities could lead to the development of reliable operation of acclerators such as the proposed UK neutrino factory or the proposed International Linear Collider. Outside of the academic research community if the same technology could be made to work with high-temperature superconductors it could allow for the development of compact room-temperature accelerators which would greatly reduce the cost of linear accelerators or synchrotrons which currently find application in a range of industries including industrial manufacture, security and healthcare. |
